// Starts and resumes a coroutine in a given thread.
//
// To start a coroutine, you first create a new thread (see Newthread);
// then you push onto its stack the main function plus any arguments; then
// you call Resume, with narg being the number of arguments. This call
// returns when the coroutine suspends or finishes its execution. When
// it returns, the stack contains all values passed to Yield, or all
// values returned by the body function. Resume returns (true, nil) if the
// coroutine yields, (false, nil) if the coroutine finishes its execution
// without errors, or (false, error) in case of errors (see Pcall).
//
// In case of errors, the stack is not unwound, so you can use the debug
// API over it. The error message is on the top of the stack.
//
// To resume a coroutine, you remove any results from the last Yield,
// put on its stack only the values to be passed as results from the yield,
// and then call Resume.
